SM15T68CA Description

Short technical summary and product information.

The SM15T68CA is a bidirectional Zener-type TVS diode manufactured by STMicroelectronics. It is designed to protect sensitive electronics from voltage transients with a reverse standoff voltage of 58.1V and a maximum clamping voltage of 121V at peak pulse current. It can handle a peak pulse power of 1.5kW (8/20µs waveform) and a peak pulse current of 83A.

 

This TVS diode is a general-purpose device suitable for a wide range of circuit protection applications. It features a single bidirectional channel, making it ideal for protecting data lines or power rails where polarity is not a concern. The device operates over a temperature range of -55°C to 150°C (junction).

 

The SM15T68CA is offered in a surface-mount DO-214AB (SMC) package, which is widely used for compact designs. The supplier device package is SMC. It is RoHS3 compliant and has a moisture sensitivity level of 1 (unlimited), though these compliance statements are unverified and should be confirmed with the manufacturer.
